NAME
openssl-skeyutl - opaque symmetric keys routines
SYNOPSIS
Header "SYNOPSIS" \fBopenssl skeyutl
[-help]
[-cipher cipher]
[-skeymgmt skeymgmt]
[-skeyopt opt:value]
[-genkey]
[-provider name]
[-provider-path path]
[-provparam [name:]key=value]
[-propquery propq]
DESCRIPTION
Header "DESCRIPTION" Not all cipher implementations support keys as raw bytes. E.g. PKCS#11 tokens
can store them internally without any option to get the raw byte representation.
This tool is designed for managing opaque symmetric keys.
OPTIONS
Header "OPTIONS" -help 4
Item "-help" Print out a usage message.
"-cipher cipher" 4
Item "-cipher cipher" The cipher to generate the key for.
"-skeymgmt skeymgmt" 4
Item "-skeymgmt skeymgmt" Some providers may support opaque symmetric keys objects. To use them, we need
to know the skeymgmt. If not specified, the name of the cipher will be used.
.Sp
To find out the name of the suitable symmetric key management,
please refer to the output of the \*(C`openssl list -skey-managers\*(C' command.
"-skeyopt opt:value" 4
Item "-skeyopt opt:value" To obtain an existing opaque symmetric key or to generate a new one, key
options are specified as opt:value. These options can't be used together with
any options implying raw key either directly or indirectly.
-genkey 4
Item "-genkey" Generate a new opaque key object.
"-provider name" 4
Item "-provider name" 0
"-provider-path path" 4
Item "-provider-path path" "-provparam [name:]key=value" 4
Item "-provparam [name:]key=value" "-propquery propq" 4
Item "-propquery propq" See "Provider Options" in openssl\|(1), provider\|(7), and property\|(7).
